This EArly-concept Grant for Exploratory Research (EAGER) project brings together a multidisciplinary team of control engineers, biomedical engineers, medical researchers, and clinicians to explore a novel pulmonary-independent method for supplementing gas exchange in an animal. Specifically, the research team will study whether the circulation of oxygenated perfluorocarbon (PFC) through the abdomen (the peritoneal cavity) of a large animal, can serve as a pathway for clearing carbon dioxide (CO2) from the animal’s bloodstream; and what are the governing dynamics of this CO2 clearing process. The peritoneal cavity essentially acts as a “third lung” in this scenario, providing critical life support for patients whose compromised lung function has exceeded the support achievable through mechanical ventilation. There is currently a critical need for this treatment, within the context of the COVID-19 pandemic, but this system also has potential to emerge as a standard modality in the critical care of hundreds of thousands of patients in pulmonary failure. Furthermore, the medical community will benefit from the deep fundamental understanding of the CO2 removal capabilities of peritoneal oxygenated PFC circulation, which will be an essential element in bringing this technology into future clinical trials.This project addresses the challenge of building an experimentally validated model of the dynamics of carbon dioxide transport from the bloodstream of a large animal into oxygenated perfluorocarbon perfused through the animal’s abdominal (peritoneal) cavity. Using the experimental data obtained as part of this project, the team will develop and parameterize a control-oriented, multi-compartment model of the transport dynamics governing CO2 removal. While previous experiments on peritoneal oxygenated PFC circulation have predominantly examined quasi-steady conditions, the research team will ensure the richness of its data by deliberately designing the underlying experiments to maximize the identifiability of the CO2 removal dynamics. The result will be a dataset better suited for the modeling and estimation of underlying system dynamics than the quasi-steady datasets. The system dynamics and control community will benefit from the opportunity to apply its scientific tools and methods to the dynamic modeling of a novel ventilation technology. Particularly important is the degree to which such modeling can help broaden the interdisciplinary impact of the dynamic systems and controls discipline to a new health-related application technology. Addressing this research challenge urgently, but rigorously, has the potential to provide critical assistance to the medical research community, particularly considering the COVID-19 crisis.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

EARLY概念探索性研究资助（EAGER）项目汇集了控制工程师，生物医学工程师，医学研究人员和临床医生的多学科团队，以探索一种新的非肺依赖性方法来补充动物的气体交换。具体来说，研究小组将研究通过大型动物腹部（腹膜腔）的含氧全氟化碳（PFC）循环是否可以作为从动物血液中清除二氧化碳（CO2）的途径;以及这种CO2清除过程的控制动力学是什么。在这种情况下，腹膜腔基本上充当“第三肺”，为肺功能受损超过通过机械通气可获得的支持的患者提供关键的生命支持。在COVID-19大流行的背景下，目前迫切需要这种治疗，但该系统也有可能成为数十万肺衰竭患者重症监护的标准模式。此外，医学界将受益于对腹膜充氧PFC循环的CO2去除能力的深刻基本理解，这将是将这项技术带入未来临床试验的一个重要因素。该项目解决了建立一个实验验证的模型的挑战，该模型模拟了二氧化碳从大型动物的血流中转运到充氧全氟化碳中的动力学，动物的腹腔。 使用作为该项目的一部分获得的实验数据，该团队将开发和参数化一个面向控制的，多室模型的运输动力学控制CO2去除。虽然先前关于腹膜含氧PFC循环的实验主要研究了准稳态条件，但研究团队将通过故意设计基础实验来确保其数据的丰富性，以最大限度地提高CO2去除动力学的可识别性。其结果将是一个数据集更适合建模和估计的基础系统动态比准稳态数据集。系统动力学和控制界将受益于将其科学工具和方法应用于新型通风技术的动态建模的机会。特别重要的是，这种建模可以帮助扩大动态系统和控制学科的跨学科的影响，以一个新的健康相关的应用技术的程度。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
